Across the continent of Preternia, the mightiest of King Grayskull's Knights was Sir Laser-Lot, a master of weapons and hand-to-hand fighting techniques. He wore an enchanted suit of armor powered by the great Gem of Tamadge which enhanced his strength and let him unleash powerful energy blasts. So legendary were his deeds that the future king He-Man sent one of his loyal Time Agents into the past to bring Sir Laser-Lot forward to his time. Here, Sir Laser-Lot became the King's new Man-At-Arms, training both the Royal Guards and the King's young son Dare in ancient battle techniques. Sir Laser-Lot uses his energy blade to fight for chivalry and justice in any time.
